Two way valves 2TGB.F and three way valve 3TGB.F with cast iron body and brass plug can be motorized by MVE actuators. These valves can be used either for control or fluid detection in air-conditioning, thermoventilation and heating plants, both environmental and industrial, and in machines for product thermal process. Three-way valves should be used only as mixing valves; angle way should never be used for control purposes. The valve body is made of grey cast iron (EN1561 GJL-250). The plug is in brass (EN12164 CW614N) with equal-percentageprofile on direct way and linear on angle way.
